1 Claim.

This invention relates to a hinge construction capable of general use.

The principal objects of the invention are to provide a pivot rod onwhich the swinging member is carried which will be fixed in position andwill not be loosened by the operation of the swinging member, so that amost desirable construction isprovided; to provide friction means of avery simple and inexpensive character bearing on the pivot rod so thatthe swinging member will be held by friction in any position in which itmay be placed, and to provide a construction in which the pivot rod isreadily removable.

Other objects and advantages of the invention will be hereinafterdescribed.

Reference is to be had to the accompanying drawing, in which Fig. 1 is afront elevation of an electric light bracket with a shade hinged to it,with the hinge constructed in accordance with this invention;

Fig. 2 is an end view of the same;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2, and

Fig. 4 is a sectional view through the pivot rod on the line 4-4 of Fig.2.

Although the invention is capable of general use, it is shown as appliedto an electric light construction where the swinging member constitutesa shade for the light, which may be a reading lamp or the like.

In such a construction, a support is provided on which the casing 11 islocated and, although not shown, an electric lamp is located between thetwo ends of the casing and occupies most of the space therein. Thiscasing is shown as formed of sheet metal and shown open at one side toallow the light to be projected from that side. The casing is shown ashaving its bottom and top walls horizontal and parallel. The top wallsupports the shade 12.

At the opposite ends near the front there are a pair of sheet metalbrackets 13 bent under the top wall of the casing and secured thereto byfriction preferably, so that they can be removed,

F but will stay in place unless it is desired to remove them. Each ofthese brackets has a vertical ear 9 centrally perforated. Through theseperforations passes the pivot rod 14. At each end of the pivot rod it isscrew-threaded and a nut 15 applied or one end can have a fixed head,but if a nut is used on each end, one of them is soldered or otherwisesecured to the ear. One nut is loose preferably for convenience inassembly.

The shade, or swinging part, 12 is also shown as of sheet metal and bentinwardly at 16 at right angles to its main part. This flange 16 iscurved around at the bottom and terminates in an inner flange 17parallel with the flange 16 which projects back into contact,preferably, with the under side of the shade. The edge of Serial No.569,823

this flange can be secured to the body of the shade if desired and it isprovided with two ears 18 at its ends which project across into contactwith the flange 16. In this way a closed receptacle is formed by theseflanges which is hollow and rigid with respect to the shade.

- In the bottom of this receptacle the pivot rod 14 is located and infact the part that connects the two flanges 16 and 17 is bent aroundthis pivot rod and preferably touches it throughout half thecircumference.

For the purpose of applying friction, a flat piece 20 of spring metal isprovided bent into zig-zag shape and alternately engaging the pivot rodand the under side of the shade 12. It is so constructed and temperedthat it always applies a friction to the rod, the reaction taking placeagainst the under side of the shade. This extends across the receptaclebetween the flanges 16 and 1'7 so that it cannot get out of place and italso extends substantially throughout the length of this receptaclepractically to the flanges 18 on each end.

It will be seen that this exerts constant friction on the rod in allpositions of the shade about the rod as a center. The rod does not turn.After long usage there will be no variation'in the amount of friction onit on account of wear, or any change in position of the parts, and itconstitutes an extremely durable, simple and inexpensive constructionfor holding the shade in any position in which it may be placed, twopositions being indicated in Fig. 2. It is capable of use for lampshades of various characters and even for doors and box covers ofvarious kinds.

Although I have illustrated and described only one form of theinvention, Iarn aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claim. Therefore, I do not wish to belimited to all the details of construction herein shown and described,but what I do claim is:-

As an article of manufacture, a pivot construction comprising astationary rod, 2. member adapted to turn on the rod having a receptacleintegrally formed at the end thereof in which the stationary rod islocated and a spring extending along the rod in said receptacle having aplurality of alternate projections in two directions, the projectionsextending in one direction bearing on the stationary rod and thoseextending in the opposite direction bearing on the said member.
